Ultra-fine iron ore tailings were modified through thermal activation, and then together with some waste rock were taken for mixed calcination. With the mass ratio of iron ore tailings to waste rock, calcination temperature and calcination time as variables, and the compressive strength of specimens and the content of chemically bound water as the objectives for optimization, an orthogonal experiment was carried out to analyze the sensitivity and influence trends of each factor on the target values, and the hydration products of the cemented materials were also analyzed. The results indicate that with an increase in the mass of waste rock, the specimen compressive strength initially increases and then decreases. As the calcination temperature rises, the specimen compressive strength monotonically decreases. As calcination time is prolonged, the specimen compressive strength first decreases and then increases. In consideration of both calcination cost and material performance, an optimal calcination scheme is finally determined, including iron ore tailings and waste rock in a mass ratio of 7∶3, a calcination temperature of 800 ℃, and a calcination time of 2 h. Under these conditions, the 3-day, 7-day and 28-day compressive strengths of the specimens can reach 4.18, 6.36 and 9.87 MPa, respectively. The main hydration products of the cemented materials are calcium silicate hydrate gel, rankinite, ettringite and hydrotalcite.

采用热活化方式对超细铁尾砂进行改性，在铁尾砂中加入废石进行混合煅烧制备充填胶凝材料，以铁尾砂与废石质量比、煅烧温度和煅烧时间为变量，试件抗压强度和化学结合水含量为优化目标，采用正交试验法研究各因素对目标值的敏感性以及影响趋势，并对胶凝材料水化产物进行分析。结果表明，随着废石质量增加，试件抗压强度先增加后降低；随着煅烧温度升高，试件抗压强度单调降低；随着煅烧时间增加，试件抗压强度先降低后增加。综合考虑烧制成本及材料性能，确定适宜的煅烧方案为：铁尾砂与废石质量比7∶3，煅烧温度800 ℃，煅烧时间2 h。在该条件下，试件3、7、28 d抗压强度分别达到4.18、6.36、9.87 MPa，胶凝材料水化产物主要为水化硅酸钙凝胶、硅钙石、钙矾石和水滑石。

采用热活化方式对超细铁尾砂进行改性，在铁尾砂中加入废石进行混合煅烧制备充填胶凝材料，以铁尾砂与废石质量比、煅烧温度和煅烧时间为变量，试件抗压强度和化学结合水含量为优化目标，采用正交试验法研究各因素对目标值的敏感性以及影响趋势，并对胶凝材料水化产物进行分析。结果表明，随着废石质量增加，试件抗压强度先增加后降低；随着煅烧温度升高，试件抗压强度单调降低；随着煅烧时间增加，试件抗压强度先降低后增加。综合考虑烧制成本及材料性能，确定适宜的煅烧方案为：铁尾砂与废石质量比7∶3，煅烧温度800 ℃，煅烧时间2 h。在该条件下，试件3、7、28 d抗压强度分别达到4.18、6.36、9.87 MPa，胶凝材料水化产物主要为水化硅酸钙凝胶、硅钙石、钙矾石和水滑石。

Ultra-fine iron ore tailings were modified through thermal activation, and then together with some waste rock were taken for mixed calcination. With the mass ratio of iron ore tailings to waste rock, calcination temperature and calcination time as variables, and the compressive strength of specimens and the content of chemically bound water as the objectives for optimization, an orthogonal experiment was carried out to analyze the sensitivity and influence trends of each factor on the target values, and the hydration products of the cemented materials were also analyzed. The results indicate that with an increase in the mass of waste rock, the specimen compressive strength initially increases and then decreases. As the calcination temperature rises, the specimen compressive strength monotonically decreases. As calcination time is prolonged, the specimen compressive strength first decreases and then increases. In consideration of both calcination cost and material performance, an optimal calcination scheme is finally determined, including iron ore tailings and waste rock in a mass ratio of 7∶3, a calcination temperature of 800 ℃, and a calcination time of 2 h. Under these conditions, the 3-day, 7-day and 28-day compressive strengths of the specimens can reach 4.18, 6.36 and 9.87 MPa, respectively. The main hydration products of the cemented materials are calcium silicate hydrate gel, rankinite, ettringite and hydrotalcite.

据统计，我国铁尾砂年产量约6亿t[1]。尾砂中含有大量重金属和选矿药剂，长期堆放在地表不仅占用大量土地，同时对周边环境造成污染[2-3]，有必要采用经济、安全、科学的方式进行尾砂处理。尾砂具有良好的均一性及惰性特质，处理后常用作建筑骨料、胶凝材料、充填骨料等[4]。将尾砂制备成胶凝材料，不仅可以提高尾砂利用率，还可以提高矿山经济效益。一般尾砂越细，其潜在活性越高，将其制备成胶凝材料的潜力越大[5]。众多学者对尾砂活性进行了大量研究，尾砂活化的主要方法[6-9]有机械活化、热活化等。研究发现机械活化很难有效提升超细铁尾砂活性，而热活化可以使超细铁尾砂中黏土质分解，形成无定形相，从而提高其活性[10]。然而，铁尾砂的热活化是多变量的，铁尾砂性质、混合料类型、煅烧温度、煅烧时间等因素都可能对其活性产生影响。鉴于此，本文通过在铁尾砂中添加废石，以铁尾砂与废石质量比、煅烧温度和煅烧时间为变量，以试件抗压强度和化学结合水（CBW）为优化目标，采用正交试验研究各因素对目标值的敏感性以及影响趋势，并对胶凝材料水化产物进行分析，以此研究铁尾砂热活化性能。

1.1　试验材料
试验材料包括铁尾砂、采石场废石及矿渣。铁尾砂和废石均取自辽宁某铁矿，矿渣购自辽宁某钢铁厂。采用X射线荧光光谱仪、X射线粉末衍射仪和Mastersizer 2000激光粒度仪对原材料化学成分、矿物成分及粒径分布进行分析，检测结果如表1、图1及图2所示。铁尾砂主要元素组成为Si、Fe、Al、Mg、Ca，具备潜在的反应活性；从矿物成分上看，铁尾砂中主要包含石英和赤铁矿两种结晶较好的惰性矿物，因此需要对制备胶凝材料的铁尾砂进行活化处理；铁尾砂中值粒径d50=18.6 μm，粒径小于50 μm的颗粒占比约48%，（28～50）μm粒级的颗粒占比约25.5%，粒径大于74 μm的颗粒占比约8.5%，属于超细铁尾砂。废石主要化学成分为CaO、MgO以及少量Al2O3，其矿物成分主要为白云石和方解石，还含有少量纹石等矿物。矿渣主要化学成分为SiO2、CaO以及MgO，以非晶相为主，其粒度大于铁尾砂但小于废石。
1.2　试验方案
直接煅烧铁尾砂制备胶凝材料的煅烧温度高，生产成本较高；铁尾砂与废石混合后煅烧，可达到协同增效、降低煅烧温度的目的。预试验和相关研究发现，影响铁尾砂活性的关键因素为铁尾砂与废石质量比（因素A）、煅烧温度（因素B）、煅烧时间（因素C），设计三因素正交试验，如表2所示。混合料在完成煅烧后再与矿渣按1∶1质量比球磨5 min制备干料，干料粒径小于0.104 mm。
1.3　试验步骤
将制备的干料与水按质量比2∶1混合搅拌成均匀料浆，注入直径5 cm、高5 cm的圆柱形模具中，在温度（20±1）℃，湿度不低于95%的标准养护环境中养护至目标龄期，脱模，测试试件力学性能。采用微机控制电子万能试验机检测抗压强度，每组试验共检测3个试件，取其平均值作为该组最终抗压强度。
完成抗压强度测试后收集试件碎块，使用异丙醇浸泡12 h以终止碎块水化，在40 ℃下将碎块烘干，使用研钵将碎块研磨并通过0.074 mm筛网用于热重测试。采用综合热分析仪以10 ℃/min升温速率测试碎块在30～600 ℃范围内的热重曲线，根据式（1）计算碎块化学结合水（CBW）含量。
式中：SCBW为碎块化学结合水含量（质量分数），%；M50和M550分别为碎块在50 ℃和550 ℃时的质量，g。
部分试件被进一步磨细，过0.074 mm筛后，采用SmartLab X射线衍射仪以5（°）/min的扫描速率测定试件在5°～50°范围内XRD图谱。
2　试验结果分析
收起
2.1　胶凝材料抗压强度
2.1.1　抗压强度极差分析
按照正交试验设计，试件3、7、28 d抗压强度测试结果和极差分析结果如表3～4所示。
各因素耦合作用对试件不同龄期抗压强度影响规律如图3所示。试件抗压强度均随着废石含量（质量分数）增加先增大后减小，铁尾砂与废石质量比7∶3时，试件抗压强度达到峰值。随着煅烧温度升高，试件抗压强度表现出单调下降的趋势，煅烧温度从800 ℃升至900 ℃时，试件抗压强度下降幅度较小；从900 ℃升至1 000 ℃时，试件抗压强度下降明显，降幅较大。试件抗压强度随着煅烧时间延长先减小后增加，但整体相差不大。从极差结果来看，在各养护龄期内，煅烧温度对试件抗压强度影响最大，铁尾砂与废石质量比次之，煅烧时间对试件抗压强度影响最小。
综合考虑成本等因素，结合表3和图3，选择试件抗压强度适宜组合为A2B1C2，即铁尾砂与废石质量比7∶3、煅烧温度800 ℃、煅烧时间2 h。
2.1.2　抗压强度方差分析
试件抗压强度与各因素的方差分析结果如表5所示。3个因素对试件抗压强度的影响规律在养护龄期上具有一致性。因素B对试件抗压强度的影响显著；因素A和因素C对试件抗压强度的影响不显著，且影响程度接近。因此，3个因素影响程度排序为：B>A>C。综合来看，不同养护龄期下，煅烧温度对试件抗压强度的影响都显著高于铁尾砂与废石质量比和煅烧时间的影响。
2.2　CBW含量
2.2.1　CBW含量极差分析
试件养护3、28 d时CBW含量与极差分析结果见表6～7。
各因素对不同龄期试件中CBW含量影响规律如图4所示。各因素对试件CBW含量影响规律与其对试件抗压强度影响规律一致。试件CBW含量随着废石含量增加先增大后减小；随着煅烧温度升高，CBW含量单调下降；随着煅烧时间延长，CBW含量先减小后增加。养护龄期增至28 d时，煅烧温度和煅烧时间对试件CBW含量的影响程度降低，说明随着养护龄期增加，煅烧温度和煅烧时间对试件中CBW含量的影响不显著。比较各因素R值，各因素对试件CBW含量影响从大到小排序为：B>A>C，适宜的组合为A2B1C2，即铁尾砂与废石质量比为7∶3，煅烧温度为800 ℃，煅烧时间为2 h。
2.2.2　CBW含量方差分析
CBW含量方差分析如表8所示。在相同养护龄期下，因素A和因素C对CBW含量影响不显著，因素B对CBW含量影响显著。根据表8中的F值可得，因素B影响最大，因素A次之，因素C影响最小，与极差分析结果一致。
2.3　水化产物类型分析
根据试件抗压强度和CBW含量分析结果，确定热活化铁尾砂的适宜组合为A2B1C2，即铁尾砂和废石质量比为7∶3，煅烧温度为800 ℃，煅烧时间为2 h。为探明其水化机理，对不同龄期的水化样品进行了XRD测试，结果如图5所示。
由图5可知，煅烧后铁尾砂中存在大量惰性石英结晶，导致试件抗压强度较低。氢氧化钙是由废石煅烧分解形成的氧化钙与水反应形成，其连续反应如式（2）～（4）所示[11]。
氢氧化钙不仅能提高溶液碱度，促进无定形相物质溶解，还能与煅烧铁尾砂发生火山灰反应，形成具有胶凝性质的水化硅酸钙凝胶[12]。碳酸钙的存在说明废石中碳酸钙在高温煅烧下并没有完全分解，还存在少量残留。钙矾石作为水化产物之一，仅在养护28 d后观察到微弱的衍射峰。这是由于矿渣含有少量硫酸根，不利于钙矾石的形成与结晶，因此经过较长反应时间才观察到少量钙矾石[13]。矿渣和废石中含量较高的MgO有助于形成水滑石，因此观察到了水滑石的衍射峰，但可能由于结晶度较差，水滑石的衍射峰强度相对较低[14-15]。
3　结论
收起
1）铁尾砂与废石质量比、煅烧温度和煅烧时间对铁尾砂试件抗压强度影响敏感性程度为：煅烧温度>铁尾砂与废石质量比>煅烧时间。适宜组合为铁尾砂与废石质量比7∶3，煅烧温度800 ℃，煅烧时间2 h。在此条件下，试件3、7、28 d抗压强度分别达到了4.18、6.36、9.87 MPa。
2）各因素对CBW含量影响敏感性与其对抗压强度影响敏感性一致：煅烧温度>铁尾砂与废石质量比>煅烧时间，但随着养护时间延长，铁尾砂与废石质量比和煅烧时间对试件CBW含量影响逐渐减小。
3）试件水化产物主要为水化硅酸钙凝胶、硅钙石、钙矾石和水滑石，其中钙矾石和水滑石随着养护时间延长结晶度逐渐增加，表明试件持续水化，不断完善和调整微观结构，在提高试件整体性能上起着关键作用。
